BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt fastener for fixing a load loaded on a vehicle or the like, and more particularly to an improvement of a belt fastener with a winding device capable of storing a belt when not in use.

[0002]

2. Description of the Related Art Conventionally, in order to fix a load loaded on a vehicle or the like, one end of a belt stretched over the load is wound around a winding shaft of a fastener, and an operation lever is rotated. The winding shaft is rotated in the belt winding direction by the action of the ratchet gear, and the belt wound around the winding shaft is wound and tightened. However, since such a fastener has a belt of a considerable length, when not in use, the long belt rather hinders the work, and is often damaged by being tangled or stepped on.

Therefore, a belt fastener with a winding device capable of easily storing the belt when not in use has been proposed, for example, in Japanese Utility Model Laid-Open No. 2-65738. This is because when the belt is pulled out from the winding device of the fastening tool and wrapped around the load, and the locking means such as locking metal fittings attached to one end of the belt are connected to the vehicle, etc. The part is wound on the winding shaft by a spring means which constantly biases the winding shaft in the belt winding direction. In this state, the operating member is reciprocally rotated in the counterclockwise direction and the clockwise direction, thereby forcibly rotating the winding shaft intermittently in the belt winding direction, and tightening the belt to tighten the load. It has become.

[0004]

However, in the fastener disclosed in Japanese Utility Model Laid-Open No. 2-65738, when the winding shaft is rotated in the belt winding direction to tighten the belt, the operating member is operated. The operation member must be turned at least three steps in order to tension the belt and maintain the belt tension state as it is, and there is a problem that the operation is troublesome.

[0005] That is, so that the belt can be pulled out freely.
After holding the supporting ratchet and the operating ratchet in a disengaged state with the ratchet teeth, and wrapping the belt over the load, first, the operating member is moved in the belt withdrawing direction so that the supporting ratchet and the operating ratchet are engaged with the ratchet teeth. Is rotated, and then the operation ratchet is rotated in the belt winding direction while being engaged with the ratchet teeth to retighten the belt. Further, the supporting ratchet is pressed from the outside by a pressing piece formed on the operating member, and the supporting ratchet is engaged with the ratchet teeth so as to maintain the rotation locked state in which the belt is prevented from rotating in the belt withdrawing direction. The member had to be turned in the belt withdrawal direction.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problem, and it is possible to sufficiently tighten and wind a belt only by rotating the operating member once in one direction without rotating the operating member a plurality of times. An object of the present invention is to provide a belt fastener with a winding device that enables a shaft to be held in a rotationally locked state in a belt withdrawal direction.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is to provide a base, a winding shaft rotatably supported by the base and urged in a belt winding direction by a spring means, and the winding shaft. A ratchet tooth connected to a shaft, an operating member rotatably supported by the base, an engaging member supported by the operating member and capable of meshing with the ratchet tooth, and the engaging member being attached to the ratchet tooth. The base has a first guide portion which is held in a non-meshed state and a second guide portion which meshes with the ratchet teeth and further enables forcible rotation of the winding shaft in the belt winding direction. A guide hole, a lock means capable of locking the operation member to a base in a state where the engagement member is in the second guide portion,
A belt sliding contact member attached to the swinging portion of the operating member and having one end slidable against an intermediate portion of a belt wound around a winding shaft, and rotating the operating member in a belt winding direction. This is achieved by a belt tightening device with a winding device in which the winding shaft winds up the belt by operating the belt, and the belt sliding contact member applies tension to the belt.

[0008]

According to the above construction of the present invention, when not in use, the belt is wound and stored on the winding shaft. Next, when the load is fixed to the vehicle body with a belt, first pull out the belt from the belt fastening tool, hang it over the load, and connect the locking means such as the locking fitting attached to one end of the belt to the vehicle body etc. I do. At this time, excess slack of the belt pulled out is taken up by the winding shaft by the urging force of the spring means.

In this state, when the operating member is rotated in the belt winding direction from the operation starting point to tension the belt, the operating member is movably supported by the operating member, and the guide hole is a long hole formed in the base. The inserted engaging member moves from the first guide portion to the second guide portion along the guide hole, and engages with the ratchet teeth connected to the winding shaft.

When the operating member is further rotated in the belt winding direction to the final operation point, the engaging member moves to the second guide portion along the guide hole, forcing the winding shaft in the belt winding direction. With the rotation, the belt sliding contact member moves in a direction for applying tension to the belt intermediate portion. Then, the belt wrapped around the load is drawn into the winding shaft, and tension is applied by the belt sliding contact member to be firmly tightened, thereby tightening the load. When the engaging member reaches the second guide portion, the operating member is locked to the base by locking means for holding the operating member in this state with respect to the base, so that the tightened state of the belt is maintained. You.

When the belt is released from the tightened state, the locking means is released to make the operating member movable, and the operating member is rotated to the operation starting point to move the belt sliding contact member in the tension releasing direction. At the same time, when the engaging member is separated from the ratchet teeth, the rotation of the winding shaft is free, and the tightening of the belt is released. When the locking means of the belt connected to the vehicle body or the like is released, the belt is wound around the winding shaft by the urging force of the spring means and stored.
